Sorry, but I really don't know what you're telling me here. I'm not a coder

Can you give me a hint by pasting what the entire plugin code should look like? It'll be easier for me to dissect it carefully from there.

Ok, I tried this:

$blocklist = array_merge($blocklist, array(
    'mymodification' => array(
        'class' => 'Shelfari',
        'title' => 'My Shelfari Bookshelf',
        'hook_location' => 'profile_left_last'
    )
));

class vB_ProfileBlock_Shelfari extends vB_ProfileBlock
{
    var $template_name = 'memberinfo_block_shelfari';

    function confirm_empty_wrap()
    {
        return false;
    }

    function confirm_display()
    {
        return ($this->block_data['shelfari'] != '');
    }

    function prepare_output($id = '', $options = array())
    {
$var = $this->profile->userinfo['field44'];
        $this->block_data['shelfari'] = '<embed width="700" height="700" src="http://www.shelfari.com/ws/shelf.swf" wmode="transparent" FlashVars="UserName' . $var . '&ShelfType=list&verE=s1.5&ListType=isowned&booksize=large&AmazonAssociate=taljes-20&Alpha=0&BGColor=FFFFFF"></embed>';
    }
}

now, the output works except one more problem:

The actual widget is giving an error stating that a username was not provided and must be provided.

Fixed. I had to had the = after UserName.

Thanks Lynne.

One quick question, I'd like to make an xml plugin file so people can install this as a product. Could I trouble you to explain how this can be done?
